This paper presents a mathematical model of a magnetostrictive linear displacement transducer. Magnetostrictive displacement transducers on torsional waves are considered. The developed mathematical model is built using the COMSOL Multiphysics software package. This model takes into account all physical phenomena, such as mechanics (mechanical tension in the waveguide, the change in the physical size of the waveguide and its twisting), electricity (the flow of a current pulse through a magnetostrictive waveguide), magnetism (the magnetic field of a permanent magnet, the magnetic field created by the waveguide through which the excitation current pulse flows).

The results of the development of a computer model that allows, without conducting experimental studies of discharge processes in capacitive ignition systems of an oscillatory and aperiodic discharge, to estimate the energy efficiency of the developed and future ignition systems are presented. The proposed model is based on a theoretical description of the laws of the time variation of the discharge current and voltage in semiconductor spark plugs, taking into account the actual current-voltage characteristics of the discharges.

One of the problems in the transportation of hydrocarbons through product pipelines in the gas industry is the safe operation and uninterrupted pumping, ensuring the required rheological properties. Prevention of formation of gas hydrates by gas heating method is that, while maintaining the pressure in the gas pipeline, the temperature of the gas is maintained above the equilibrium temperature of their formation. The most advanced and promising methods used for this are electrophysical methods of thermal influence on the gas pipeline system. For example, local and locally-step heating of gas pipelines maintain the temperature of the viscous dispersed medium only in a limited area, and the associated heating of pipes requires a large consumption of electricity throughout the product pipelines. Therefore, the development of other types of inductive heaters is today an urgent task of the oil and gas industry as a whole.

In this paper, we consider a methodology for choosing the modes and duration of accelerated tests that ensure equivalence at the same time for all the main elements and characteristics of the consumption of engine service life along with direct current and alternating current generators. The determination of the modes and duration of accelerated tests of the engine and generators is carried out according to the generalized method, which allows as much as possible to ensure the equivalence of accelerated and lengthy damage tests at the same time of all “critical” elements of engine and generator assemblies. Comparative accelerated engine tests carried out under the regimes calculated by the considered method and the method used commercially in the industry showed that in the engine as a whole, the accelerated test efficiency, which was estimated by the level of equivalence of accelerated and lengthy tests, is 2 times higher, which allows more accurate assessment reliability and service life of generators and engine by accelerated testing.

Development of electric machines with high specific power is actual problem. In this case, machines with high-temperature superconducting windings on rotor and stator are the most promising. Application of high-temperature superconducting tapes for windings of electric machines is a complex problem. Machine with annular armature coils could be a solution. Inductance of windings of the machine with annular armature winding is described in this paper. Determined expressions allow choosing rational type of external magnetic shield and its dimensions. Comparison between two machines with different types of magnetic shield also described in the paper.

This article consider the studies of the stator design features influence on the submersible thyratron motors parameters. In this article a three-phase submersible thyratron motor with permanent magnets, outer diameter 81 mm with a power of 45 kW and a rotor speed of 6000 rpm was studied. Two identical submersible thyratron motor computer models were developed and calculated to determine the proposed submersible thyratron motor design effectiveness. The first submersible thyratron motor computer model considers studies for an open stator slots design; the second submersible thyratron motor computer model considers studies for a closed stator slots design.

This paper provides an overview of-fault-tolerant electric machine for transport applications. A number of motor failure cases and methods to prevent or minimize their impact on the drive system are considered. The fault tolerance of bearings, stator and rotor windings are both analysed in detail. In addition, finite element simulations of an outer rotor permanent magnet machine with a power of 4.5 kW and rated speed of 12000 rpm have been carried out. To verify the simulation results, an experimental prototype of a 6-phase permanent magnet motor for aircraft fuel pump application was developed. It is shown that the use of 6-phase (and more phases) electrical machines with permanent magnets is more effective than machines with duplex three phase system in terms of fault tolerance and efficiency. In addition, it is shown that the use of bearingless machines with permanent magnets is one of the most promising technologies for providing of fault-tolerance.
